A development program entitled “Research and Development to Commercialize an Innovative Line of Environmentally Preferable Paints and Coatings for the Marine and Aquaculture industry” was funded by Flexdel Corporation and governmental grants (Commission of Science and Technology). The purpose of this program was to further reduce copper from marine antifouling products. The result of Flexdel’s work was the Aquagard product line. Aquagard products are considered “environmentally preferable” because they release low levels of VOC’s and heavy metals compared to other competing products. Aquagard still uses cuprous oxide as its biocide. However, Flexdel Corp. has perfected and controlled the leach out rates of this compound. The result is a bottom paint that requires less copper, yet provides year round protection. The water based paint reduces the risk of toxic solvent exposure. It cleans up with soap and water and most importantly, has proven performance in the marketplace.
